As of now, there is no evidence indicating a real - life love story between Kim Woo Bin and Shin Min Ah. They may be colleagues in the entertainment industry but haven't shown any signs of a romantic relationship.
I'm not sure if Woo Young Woo is based on a specific real - person. It could be a fictional character. However, if there is a 'Woo Young Woo True Story', it might be about someone's real - life experiences that inspired the creation of a character with that name, or it could be a misnomer and there is no such true story.
If it was made into a movie, it could be a story of two people from different walks of life meeting by chance. Shin Min Ah's character might be a sweet and kind - hearted woman, while Kim Woo Bin's character could be a bit of a rebel. They would start off not getting along but then gradually fall in love through various shared experiences.
The rumored love story between Kim Woo Bin and Shin Min Ah is likely just that - a rumor. There's no official confirmation from either of them or their agencies. In the entertainment industry, such rumors can start from simple on - screen chemistry or just chance encounters at events. But without real proof, it's hard to say there's any truth to it.
I don't know the specific noh mask horror story. But generally, noh masks can be quite eerie. Their blank expressions and the way they are used in traditional noh theater, where the actors bring them to 'life' in a very stylized way, could potentially be the basis for a horror story. Maybe there could be a story where a cursed noh mask causes strange happenings to whoever possesses it, like seeing strange apparitions in the middle of the night or having a feeling of being constantly watched.
